Included is a\ntime tag (seconds since 00:00 UT of January 6, 1980), an arrival\ndirection (R.A. and Dec. in J2000 celestial coordinates), the IBEX\nlocation, ENA energy band, species (hydrogen or oxygen) and \ncoincidence type.  Data files are given for each 8-day orbit and \nfor each of the 8 IBEX-Lo energy bands.  The data files are in \nASCII.",
